摘　　要：利用国内大中城市震害矩阵为样本分析影响建筑物抗震能力的各个因素,提取出主要的震害影响因子。通过海明加权距离法计算出各城市震害矩阵之间的相似度权重,并通过灰色关联法得出各个样本城市震害矩阵与目标城市的关联度,得出差异化权重的关联度矩阵。使用得到的关联矩阵代替层次分析法中的专家打分矩阵,从而减少该方法的主观因素,使得改进层次分析法成为一种可以定量的计算方法。把海明加权距离法、灰色关联法、层次分析法分别根据其各自特点融合在一起,形成了一种全新的震害矩阵拟合算法,解决了3种方法在震害矩阵计算中的局限性。通过对上海市浦东区多层钢混结构房屋进行多元算法的震害预测证明了此种方法的可靠性和可行性。This paper analyzes the various influence factors of building aseismic capability and selects outthe main factors on basisof earthquake damage matrixes ofseveral Chinese large and medium cities. Firstly, we calculate theearthquake damage matrix similarityweightingof each citythrough weighted hamming distance method, and then calculate associationdegree between the earthquake damage matrix and the target cityth- rough grey correlation method, and finally obtain differential weighting correlation matrix. Using the inci- dence matrix instead of expert scoring matrix in the analytic hierarchy process （AHP）, it can reduce the subjective factors of the method and make itquantitative. Blending together the weighted hamming distance method, grey correlation method, analytic hierarchy process （AHP） according to their respective charac- teristics, the new fitting method for earthquake damage matrix solves the limitations of the three methods. The reliability and feasibility of the new fitting method is proved inmulti-storey steel structure building multivariate algorithm of earthquake damage prediction in ShanghaiPudong new area.
